In this article, we present a method for converting boundary value problems for impulsive fractional differential systems involving the Riemann-Liouville type Hadamard fractional derivatives to integral systems. The existence results for solutions of this kind of boundary value problems are established. Our analysis relies on the well known fixed point theorem. Some comments on recent published papers are made at the end of the paper.

By establishing a comparison result and using the monotone iterative technique combined with the method of upper and lower solutions, we investigate the existence of solutions for nonlinear fractional differential systems with coupled four-point boundary value problems.
